Charlie,

How is this for what was going on with the hot flyback--internal arcing short in the winding that goes down in resistance as the thing heats. The power soaked up in the short causes the HV to drop; the shunt requlator in turn tries to stabilize the HV by lowering its current, as you noted. Your mention of the hot spot on HV sort of cinches it. You need an IR non-contact thermometer as well as a non-radioshack VOM. Both Simpson 260's and Triplett 630s use a battery of the 15 to 22 volt size on the hi resistance ranges. They work great for testing all kinds of semiconductors.
